Yes, you can. You need to have one machine that can see both
networks. One machine doesn't have to see ALL networks, but you have
to have a shared machine for each network that you want to add. i.e.
say you want to have 192.168.0.x, 192.168.1.x and 192.168.2.x. Unless
you have a machine that sees all three networks at once (probably
three separate network cards) none of them will be aware of the other
networks. However, if you have ONE machine which is your "central
gateway machine" which can see all three of the networks, you can
always send things through the central machine ('gatekeeper') to any
of the other networks... i.e. (please forgive the bad ascii art! <G>)
("Gatekeeper")

192.168.1.1
Anything on the 192.168.0.x network would have to go through
the eth0 (for example) of "Gatekeeper" to get to the 192.168.1.x or
192.168.2.x and vice versa. As long as your "gatekeeper" machine has
a route statement making eth1 the default gateway for 1.1 network and
eth2 for the 2.1 network, everything will be on separate networks
only reachable via the "gatekeeper" machine.
